iVPN seems top-notch for general use, but claims about P2P are misleading at best–i.e., although they say P2P is allowed, P2P upload bandwidth is nonetheless shaped (max. 100kB/s). Better than being blocked entirely, as some VPNs do, but no good if your goal is to circumvent your ISP’s traffic shaping.

They do have a solid privacy policy, though (unlike WiTopia/StrongVPN who keep logs).
